A niched Pareto genetic algorithm for multiobjective optimization
TLDR
We introduce the Niched Pareto GA as an algorithm for finding and maintaining a diverse "Pareto optimal population" on two artificial problems and an open problem in hydrosystems. Expand

Massive Multimodality, Deception, and Genetic Algorithms
TLDR
This paper considers the use of genetic algorithms GAs for the solution of problems that are both average sense misleading deceptive and massively multimodal An archetypical multimodAL deceptive problem here called a bipolar deceptive problem is de ned and two generalized constructions of such problems are reviewed.

Long Path Problems
TLDR
We demonstrate the interesting, counter-intuitive result that simple paths to the global optimum can be so long that climbing the path is intractable. Expand

The Niched Pareto Genetic Algorithm 2 Applied to the Design of Groundwater Remediation Systems
TLDR
We present an evolutionary approach to a difficult, multiobjective problem in groundwater quality management: how to pump-and-treat contaminated groundwater to remove the most contaminant at the least cost. Expand

TLDR
Genetic algorithms (GAs) with "fitness sharing" have been analyzed and successfully applied to problems in search and optimization, while GAs using various types of "resource sharing" are incorporated into classifiers, immune system models, artificial ecologies, artificial economies, etc. Expand

Multi-objective optimal design of groundwater remediation systems: application of the niched Pareto genetic algorithm (NPGA)
Abstract A multiobjective optimization algorithm is applied to a groundwater quality management problem involving remediation by pump-and-treat (PAT). The multiobjective optimization framework usesExpand

Implicit Niching in a Learning Classifier System: Nature's Way
TLDR
We approach the difficult task of analyzing the complex behavior of even the simplest learning classifier system (LCS) by isolating one crucial subfunction in the LCS learning algorithm: covering through niching. Expand
